Just bought a 335, can someone address a few concerns for me?

miringrains · 03-23-2013, 03:14 PM

The car is a 2010 with 68k miles on it. The turbos are 100% and the engine runs 100%. Only thing that bothers me is this diesel engine sound coming from the engine.. very subtle but I noticed it on a lot of n54s.. how can I fix that?

That's a byproduct of having direct injection with a 200bar fuel system. Nothing you can do about it.

stop puttin diesel in it. try 93 only if you have it. or try e85 mixed with unleaded. some people on here think diesels ok, but it could make the car stumble and sound like a diesel. I wouldn't use diesel any more.

That's how our injectors sound unfortunately, not much we can do about it beside getting an exhaust system to cover the sound
